Method of and apparatus for amplifying heat

Abstract

A method and apparatus, wherein heat is absorbed from a first heat medium in a heat source circulating circuit, by way of an evaporator, discharge of heat in a condenser from a second heat medium rendered to a high pressure and high temperature state in a compressor is restricted in a heat pump circuit to maintain the temperature for the heat medium recycled from the condenser to the evaporator at a relatively high set temperature and, while on the other hand, the remaining amount of the heat discharged from the condenser in the heat pump circuit is absorbed and accumulated through a heat medium circulating circuit through which a third heat medium is circulated and a portion of the heat thus obtained is supplied to the heat medium in the above heat source circuit to maintain the heat medium in the heat source circuit within a range of set temperature higher than the temperature of the heat medium jetted into the evaporator in the above heat pump circuit, to thereby obtain heat at high temperature from the circulating circuit for the third heat medium.

What is claimed is: 
     
       1. A method of amplifying heat comprising: transferring heat from a first heat source circuit (E) to a second heat medium recycled through a recycling type heat pump circit (D) in an evaporator and raising said second heat medium to a high pressure and high temperature by a compressor,   restricting heat discharge from said second heat medium at the high pressure and high temperature in a condenser of said heat pump circuit (D) to maintain the temperature of said second heat medium jetted out through an expansion valve to said evaporator at a relatively high set temperature depending on the performance of said compressor,   transferring the heat other than that used for maintaining said second heat medium at said set temperature from the condenser to a third heat medium by way of a heat utilizing circuit (F) and circulating said third heat medium in said heat utilizing circuit (F) to said condenser, thereby successively accumulating heat therein to a predetermined safety temperature,   feeding back a portion of the heat in said third heat medium accumulated in said heat utilizing circuit (F) to said first heat medium in said heat source circuit (E), thereby increasing the temperature of said first heat medium to a predetermined temperature higher than the temperature of the second heat medium jetted into the evaporator in the heat pump circuit, and   stopping the compressor whenever the temperature of the third heat medium reaches a predetermined value and actuating the compressor when it decreases below said predetermined value.   
     
     
       2. The method of amplifying heat as described in claim 1, further comprising, at the start of the hear pump circuit (D), if the temperature of the first heat medium in the heat source circuit (E) is lower than a further predetermined temperature, additionally heating said first heat medium so that the temperature thereof is higher than the temperature of said second heat medium jetted into the evaporator.
